We are certainly not alone

23 years ago astronomers pointed the Hubble Space Telescope to a small dark patch in the sky that looked empty at first. This small region of sky in Ursa Major was carefully selected to be as empty as possible so that Hubble would look way beyond the stars of our own Milky Way galaxy and nearby galaxies.

The telescope spent 10 days observing this area taking 342 long exposure photos which were combined into the single image you can see above.

The results were astonishing!

The image was analyzed by scientists who found that close to 3000 galaxies can be seen on it, the major part of them didn't have time to form stars yet. Those galaxies were nothing else than dust formed soon after the Big Bang, we were looking back into the young universe.
